yes i did. The 2.4x Rh kernels actually aren't right in their swapping
behavior. it really nailed my samba server here at the house and caused
massive swapping and load issues on a friend's gaming server. i don't
know what it is about RH's 2.4x kernels but they swap and won't give the
cache memory back. I have more than 6 ipcop firewalls based on 2.4
kernels(not RH) and they won't swap unless you actually exhaust physical
memory. The issue is the RH 2.4x kernels which for some reason continue
to swap even with 500 MEGS of cache memory available to take back. 2.6x
runs much better and actually obeys the swappiness commands. Even the
various patches done by Rh on the 2.4x kernel never reduces this behavior.
I don't think I've seen that. Here is a 'top' from an RH7.3 box whose
uptime counter has rolled a couple of times so it has actually been
running several years.
10:57am up 317 days, 6:56, 6 users, load average: 0.07, 0.10, 0.09
213 processes: 210 sleeping, 2 running, 0 zombie, 1 stopped
CPU states: 5.1% user, 2.9% system, 0.0% nice, 91.8% idle
Mem: 2065404K av, 1988360K used, 77044K free, 0K shrd, 570124K buff
Swap: 1331128K av, 204848K used, 1126280K free 1158784K cached
That doesn't seem that bad and it's a 2.4.20-18.7 kernel. It's not very
busy now because it is a weekend. I never see a lot of swap-in
happening even when it is busy.
